The UK version of Dragons' Den originally premiered on BBC Two.
The business reality programme debuted in 2005, bringing entrepreneurs before a panel of wealthy investors known as Dragons. Contestants present their companies, explain their financial position and request investment in exchange for an ownership stake.
BBC Two was the programme's original home, although its popularity later made it one of the BBC's best-known factual entertainment formats. The channel is distinct from BBC One, which has generally carried the BBC's broadest mainstream audience programming.
The UK show is part of an international television format that has been adapted in many countries. Its title and investor terminology vary across editions, but the central pitch-and-investment structure remains consistent.
